Abstract
Abstract A method of forming a photographic image which comprises development processing with an alkaline aqueous activator solution a silver halide photographic light-sensitive material comprising a support having thereon at least one surface latent image type silver halide emulsion layer, and containing in at least one layer selected from a silver halide emulsion layer and another hydrophilic colloid-layer (1) a hydroquinone series developing agent and (2) an acylhydrazine compound represented by formula (I): R.sup.1 NHNHCOR.sup.2 (I) wherein R 1 represents an unsubstituted or substituted aryl group or alkyl group; and R 2 represents a hydrogen atom, or an unsubstituted or substituted aryl group or alkyl group, wherein the aqueous activator solution or a prebath thereof contains at least one compound represented by formula (II): ##STR1## wherein each of W 1 , W 2 , W 3 , and W 11 can represent a hydrogen atom, an unsubstituted or substituted alkyl group, alkenyl group, or alkynyl group, an acyl group, or a sulfonyl group, and W 1 and W 2 , or W 3 and W 11 , can be bonded to each other to form a ring; Q 1 represents --CH 2 CH 2 -- or --CH 2 CH 2 CH 2 --; and n represents an integer of 1 to 4. According to this activator type developing method, an image having good quality can be constantly obtained irrespective of the stirring conditions of the processing solution.
